Abstract

The mineralogy of metabasites of the Sierra del Puerto (prpv. Murcia) are studied in this work by X-ray diffraction. Three transversal to the basic rocks outcrop are realized with a systematic sampling of fresh and alterad mataríais. The semiquantitative mineralogical composition by X-ray methods shows a predominance of plagioclase, amphibole and epidote mineralsin little altered metabasites and an progressive increase in smectite, chlorite, swelling chlorite and smectite-chlorite regular interstratified parallelly to the transformation processes in the basic rocks.
